The French researchers reported that the more irregular carbon materials used to make supercapacitor electrodes, the greater the capacitance of the supercapacitor is and the stronger the ability to withstand high pressure.
Supercapacitor is a new type of energy storage device, which has the advantages of short charging time, high output power, long life and so on, which can be used for braking energy recovery system of vehicles. Its working principle is based on the interaction between the electrode and the positive anion in the electrolyte, the greater the electrode surface area and the stronger the interaction between the positive and negative ions, the greater the capacitance.
The French National Research Center and the University of Orleans researchers used NMR spectroscopy to quantify the electrostatic effects of electrodes and positive negative ions, the results found that the more irregular structure of carbon electrode materials, the greater the capacitance of the super capacitor, the higher the withstanding capacity of high pressure.
